Looks like I struck out again. I talked to Tenecor, said they would make the custom overflows for me. Salesman said he would email me the price info that morning. Days went by, no email, no call. I called them back, aprox 7 days later, left a message with email and phone number. Again, days went by, no email, no call.....I have a 250 gal Tenecor, love the tank, but the customer service seems to be lacking.....?
